At first glance, this math puzzle looks easy, but it can quickly confuse people who rush to find the answer. The challenge is to solve (5 + 5) × 10 − 10 ÷ 5 in just five seconds without using a calculator. Some people jump to the wrong conclusion, while others forget an important mathematical rule. Can you figure it out before reading the solution?

The secret to solving this puzzle is understanding the order of operations. In mathematics, parentheses come first, followed by multiplication and division, and finally addition and subtraction. Remember that multiplication and division have equal priority, as do addition and subtraction, so operations at the same level are performed from left to right.

Start by solving the parentheses: 5 + 5 = 10. The expression now becomes 10 × 10 − 10 ÷ 5. At this stage, it might be tempting to subtract first or simply work through the equation from left to right without considering the rules. However, multiplication and division must both be completed before subtraction.

Next, calculate the multiplication and division: 10 × 10 = 100 and 10 ÷ 5 = 2. The expression is now 100 − 2. Subtracting the two numbers gives the final result: 98. Therefore, the correct answer is 98, not 50. Following the order of operations makes the solution straightforward, even when the five-second time limit adds pressure.

So, how did you do? Did you find the answer immediately, or did you need a little more time to work through the equation? These quick math challenges are a fun way to test your concentration and refresh your knowledge of basic arithmetic. Share the puzzle with friends and family to see who can solve it correctly in five seconds. Remember, accuracy matters more than speed!
